ipc: adjust proc_ipc_sem_dointvec definition to match prototype

Commit 32927393 ("sysctl: pass kernel pointers to ->proc_handler")
changed ctl_table.proc_handler to take a kernel pointer.  Adjust the
signature of proc_ipc_sem_dointvec to match ctl_table.proc_handler which
fixes the following sparse error/warning:

  ipc/ipc_sysctl.c:94:47: warning: incorrect type in argument 3 (different address spaces)
  ipc/ipc_sysctl.c:94:47:    expected void *buffer
  ipc/ipc_sysctl.c:94:47:    got void [noderef] __user *buffer
  ipc/ipc_sysctl.c:194:35: warning: incorrect type in initializer (incompatible argument 3 (different address spaces))
  ipc/ipc_sysctl.c:194:35:    expected int ( [usertype] *proc_handler )( ... )
  ipc/ipc_sysctl.c:194:35:    got int ( * )( ... )

Fixes: 32927393 ("sysctl: pass kernel pointers to ->proc_handler")
